Fix break line formatting for vote description

[john-light]

When a word is too long for a line, the word is cut off (e.g. "Gove-rnance" seen in the screenshot below). Words should be pushed to the next text line if they are too long for the current line.

This seems to potentially be a browser or OS-level thing; both Chrome and Firefox on macOS has the correct word split here (we're actually telling it to split with a - if possible already).

It may be related to the user dictionaries that the browser uses to do the word splits.

I'll note here that this issue is still occurring in the latest Firefox on Linux Mint 18.3

This problem disappeared with the redesigned, but a similar issue appeared, which will get fixed by aragon/aragon-apps#1021

Closing now since this issue was about a previous version of the app.
